His "more":
It is flexible and adapts to virtually all apartments / houses. I used to secure a large opening. So, I especially liked that one can climb fairly loosely elements (my door is not in the middle but near the wall, for example).
Similarly, it is simple to remove (or add) the elements, into a greater or lesser barrier.
Installation is fairly simple, but it takes a minimum of tinkering since we must screw the wall fixings. Once mounted, everything is easy to use and you can dismantle all in a few seconds if you are entertaining.
Opening the door is simple, you only need one hand. Thus, the eldest can open without problems, so that the rest of the family is embarrassed a minimum while holding the baby away from hazards.
The "minus":
The concern I have with this product is that it is essential to screw the wall - so expect holes in the wall. It bothers me since it will remain in place for just over a year, maximum two. And holes, them, there will still be good after ...
I would have appreciated a screwless mounting system, or possible "pinch" the barrier to a door.
Then, but this is really high, just to mention: the choice of colors slightly reduced (black or white).
Overall, I find this really quite ideal barrier, I plan to use this summer to make sure the baby does not do anything stupid on the balcony!
